Application filed November 12, 1915. Serial No. 61,069. Renewed March 11. 1918. Serial No. 221.867.

To all whom it may concern:

Be it known that I, Roenm: J KRAUSE, a citizen of the United States, residing at Dehesa, in the county of San Diego and State of California, have invented certain new and useful Improvements in Containers and Sealing-Rings Therefor of which the following is a specification, reference being had therein to the accompanying drawing.

The invention relates especially to a container comprising a jar and a cover therefor preferably of novel construction as hereinafter described, and a sealing ring between the jar and the cover and so constructed that it can be readily disintegrated or destroyed mechanically while the cover is in place.

through a container embodying the invention Fig. 2 is a side view of the sealing ring.

Fig. 3 is a view similar to Fig. 1 but illustrating another embodiment of the invention.

Fig. 4 is a plan view of the sealing ring shown in Fig. 3.

Fig. 5 is a view but illustrating invention.

Fig. 6-shows still another embodiment of the invention, the sealing ring in this construction being similar to that shown in Fig. 4. y

Fig. 7 is an enlarged plan view of another form of sealingring.

Fig. 8 is anenlarged sectional view taken along the line 8-8. of Fig.1

Fig. 9 is an enlarged gmentary plan view of still another form of sealing ring.

Fig. 10 is an enlarged sectional view taken along the line 10--10 of Fig.9.

another embodiment of the Fig. 11 is an-enlarged fragmentary plan view of still another form of ring. 7

Referring to the drawings, especially Figs.

sinner tolFigs'J 1 and a for instance, as canned fruit. The lower part of the jar can be constructed in any usual or preferred way. In the preferred ,embodiment of the invention the upper part of the jar is provided with a conical surface at 2, preferably on the exterior. 3

represents the cover of the jar which is also of or substitute therefor, but for some classes of work the body part of. the ring can be formed'of parafiin or a similar compound.

Embedded in the bodyv of the ring is a suitable tension means which can be pulled out progressively to cause the disintegration and destruction of the ring without removing the cover from the jar. This tension means can be of any of a number of forms, I

but the form which I prefer and which I have shown in Figs. 1 and 2 comprises a flexible tension device such as a wire or. cord arranged spirally within the body of the ring. Preferably when the body of the rlng.

.is formed of rubber'thereis initially constructed a strip of unvulcanlzed rubber rectangula r-in cross section having a wire or cord 6 embedded in its center. of rubber with the wire is then wound on a suitable form to obtain the shape as shown in Figs. 1 and 2. While still heldin the form or in a suitable mold, the rubber is vulcanized so as to form a permanent ring.

When the container shown in Fig. '1 is to be used, the jar is filled with the food products toga preserved, these being preferably put in 0t inlthe usual way.; e sealing ring 5 is loosely inserted in the cover, which is cold and easily handled, and then the cover, with the sealing ring, is pushed into place on the conical part of the ar. Prefera'bly a weight is added to the top of the jar or the ar is turned upside down to bring the weight thereof on the cover so as to automatically hold the cover and ring in place until the contents has cooled. After the cooling of the contents the partial vacu- This strip um formed in the jar will prevent the removal of the cover. As shown, the cover is preferably provided with an annular rib around its periphery for the reception of a weight or to serve as a base when the jar is inverted. q

When the contents of the jar isto be used, the jar can be easily opened by simply catching hold of the projecting end 7 of the tension member of the ring. By pulling downward on this tension member the ring can be progressively unwound and pulled out, its complete destruction as a ring being thus efi'ected. It will be noted that successive annular portions of the ring are destroyed, and preferably removed, successively but that the ring is not bodily withdrawn as a whole.

It'will be observed that the glass parts of the container are very simple and present no irregular grooves and projections dificult to clean and easily broken.

It will be understood that containers embodying my invention are adapted to be used not only for domestic purposes in the preserving of fruits, etc., but also for factory made and packed products, such as canned vegetables, preserved meats, lard, butter, etc.

being re-used and can be either returned to jars in common use.

the factory or can be retained for domestic purposes.

In Figs. 3 and 4 I have shown another embodiment of the invention. The jar 1 can be the same as or similar to the Mason The cover 3 can be the usual metal cover used with the Mason jars. The sealing ring 5 is, in this case, fiat instead of conical, but can otherwise be similar to the arrangement already described.

In using the oontainer as shown in Fig. 3, the jar is filled in the usual way, the ring 5 is put in place and the cover is screwed down. When the jar is to be opened, it is only necessary to separate the loose end of the wire embedded in the ring and to unwind the ring from beneath the cover.

There is no necessity for first turning the cover thus avoiding all the difliculty attended with the attempt to do so.

In Fig. 5 I have shown a construction similar to that in Figs. 1 and 2 in that a glass cover is provided. The jar 1 and the cover 3 are provided respectively with internal threads 2" and external threads 4 adapted to be engaged with each other to hold the cover in place. Between the cover and';the top of the jar is a sealing ring 5 slmilar to that shown in Fig. 4 and adapted to be similarly used;

In Fig. 6 I have shown another'form of container especially adapted for jellies and similar products. The jar 1 is cup-like in form and the cover 3 is a metal disk, preferably having its central part depressed to leave a peripheral flange adapted to lie above the jar.- Between this flange and the top surface of the jar wall is a ring 5 similar to the ring 5. The jar is filled in the usual way and when it is to be opened, the ring 5 is unwound and destroyed in the way already described.

In Figs. 7 and 8 I have shown a sealing ring 5 in the form of a spirally wound braided cord 6 which is impregnated with a rubber compound and molded into the form of a ring after which the rubber is cured. It will be observed that in this case the cord 6 constitutes a tension means spirally embedded in the ring. This ring can be either conical or flat as required, and can be used in the way already described, being unwound by pulling on the end 7.

In Figs. 9 and 10 I have shown still another form of ring 5*, this construction being similar to that shown in Figs. 7 and 8. A braided cord 6 is provided which is wound in the form of a ring and sewed in place by transverse stitches 8'and the entire ring is impregnated with parafiin or other similar compound. The stitches 8 are relatively weak so that when the ring is to be removed from the jar by unwinding, the stitches can be easily broken.

In Fig. 11 I have shown a ring 5 having its tension means in the form of. a braided or knitted fabric so formed that it can be easily unraveled by pulling on the loose end at 7. The fabric is impregnated with paraiiin or other similar compound and can be used as before described.

What I claim is 1. A container comprising a jar, a cover for the jar, and a sealing ring between the cover and the jar having a tension means embedded therein and adapted to be withdrawn to progressively destroy and remove V successive annular portions of the ring while the cover is in place.

2. Awontainer comprising a jar, a cover for the jar, and a sealing ring betweenlthe cover and the jar having a tension means spirally embedded therein and adapted to be unwound to progressively destroy the ring while the cover is in place.

3. A container comprising a jar, a cover for the jar, and a sealing rlng between the cover and the jar having a tension means spirally embedded therein and adapted to be unwound to progressively destroy and remove the ring while the cover is in place.

4. A container comprising a jar, a cover for the jar, and a sealing ring between the cover and the jar having a wire spirally embedded therein and adapted to be unwound to progressively destroy the ring while the cover is in place.

5. A container comprising a jar having a comcaltop, a cover for the jar havin a part of the jar, and a conical sealing ring between the cover and the jar having a. tension means embedded therein and adapted to be withdrawn to progressively destroy successive annular portions of the ring While the cover is in place.

6. A container comprising a jar having an external conical surface at its top, a cover for the jar having an internal conical surface adapted to match the conical surface of the jar, and a conical sealing ring between the cover and the jar having a tension means embeddedv therein and adapted to be withdrawn to progressively destroy successive annular portions of the ring While the cover is in place.

7. As an article of manufacture, a sealing ring comprising a plastic substance and a tension means embedded therein and adapted to be withdrawn to progressively destroy ring comprising a plastic substance and a spirally arranged tension means embedded therein and adapted to be unwound to progressively destroy the ring.

10. As an article of manufacture, a seal-- ing ring comprising a plastic substance and a spirally arranged tension means embedded therein and adapted to be unwound to progressively destroy the ring, the said plastic substance adhering to the tension means as it is unwound.
